French Interior Minister Gerard Collomb confirmed on Twitter that the driver was detained.

"Support for injured young people in Blagnac, immediately taken care of by our emergency services," Collomb wrote in French on Twitter. "I salute the responsiveness of the [national police] who detained the driver. It is the investigation that will determine the nature of his act."

Local authorities are in charge of the investigation for now, the Paris prosecutor's office told ABC News.

Toulouse Prosecutor Pierre-Yves Couilleau said on BFM TV that the suspect drove his car into three students. The suspect did not resist arrest and told police his act was "deliberate and that he has been thinking about doing this the past month." Couilleau said the man has "psychological issues" and is not on France's terror watch list.
